Benefits of technology

The present invention is a regulating tank that can cool water and increase dissolved oxygen levels to help promote the growth of aerobic bacteria in a biochemical process.

Problems solved by technology

As a result, it generates large amount of wastewater in the process of paper recycling.
Typically, high temperature is bad for bacteria, and water temperature always increases in wastewater treatment.

Embodiment Construction

[0022]A wastewater treatment system of the preferred embodiment of the present invention includes a primary settling tank and a regulating tank connected to the primary settling tank through pipes. In the present embodiment, the primary settling tank is higher than regulating tank, so that wastewater flows to regulating tank from the primary settling tank by gravity.

[0023]As shown in FIGS. 1, the regulating tank includes a tank member 10. The tank member 10 has an annular wall 12 and a bottom to enclose a chamber 14 therein to receive the wastewater from the primary settling tank.

[0024]A circular pipe 20 is fixed to a top edge of the annular wall 12 of the tank member 10. A draining device 30 having a first pump 32 and a first guiding pipe 34. The first guiding pipe 34 has opposite ends connected to the first pump 32 and the circular pipe 20. The first pump 32 pumps the wastewater in the tank member 10 to the circular pipe 20 through the first guiding pipe 34.

[0025]A plurality of no...

Abstract

A regulating tank includes a tank member having an annular wall to receive wastewater. A circular pipe is connected to the tank member. A draining device drains the wastewater in the tank member to the circular pipe. A plurality of nozzles connected to the circular pipe to eject the wastewater in the circular pipe back to the tank member. When the wastewater is ejected by the nozzles, a temperature of the wastewater is reduced, and dissolved oxygen of the wastewater is increased.

Description

BACKGROUND OF THE INVENTION1. Technical Field[0001]The present invention relates to a wastewater treatment system, and more particularly to a cooling apparatus of a regulating tank.2. Description of Related Art[0002]Recycling of papers is getting more and more important in present days since shortage of natural resource is more and more serious. In order to separate fibers in waste paper and remove ink from fibers, it needs specified chemical solutions and water in aforesaid processes. As a result, it generates large amount of wastewater in the process of paper recycling.[0003]Treatments of wastewater in paper recycling including coagulation process, biochemical process, and chemical process. Bacteria, such as anaerobic bacteria and aerobic bacteria, are used in biochemical process. Environment is deeply effects the works of bacteria, such as temperature and pH value of water. Typically, high temperature is bad for bacteria, and water temperature always increases in wastewater treat...
